摘要： The disclosure pertains to methods and apparatus using V2X enhancements to perform discontinuous reception. In an embodiment, a method implemented by a first WTRU, for a device-to-device (D2D) communication between the first WTRU and a second WTRU, the method may include any of comprising receiving, from the second WTRU, D2D control information comprising: (1) first information indicating one or more first transmission resources reserved for transmission of the D2D communication and (2) second information indicating if at least one second transmission resource is reserved for retransmission of the D2D communication; determining a sleeping period for the first WTRU that ends prior to a reception time of the retransmission of the D2D communication, wherein the sleeping period is based on the second information; and receiving the retransmission of the D2D communication, after an end of the determined sleeping period.

摘要： There may be one or more systems, methods, and/or devices that address a relay wireless communication scenario. For example, in such a scenario, there may be at least three entities, a remote a wireless transmit receive unit (WTRU) may need to communicate with a network node (e.g., gNB) and/or another WTRU that it cannot directly communicate with. This remote WTRU may communicate with a relay WTRU in order to communicate with the ultimate destination (e.g., another WTRU or a network node). The use of a relay may require establishment and configuration of one or more entities involved.

摘要： Apparatuses and methods are disclosed for panel selection for uplink (UL) transmission in a multi-transmission-reception point (TRP) system. A method performed by a wireless transmit/receive unit (WTRU) may include receiving, for each of a plurality of transmit/receive points (TRPs), information for measuring a first set of reference signals and spatial relation information, the spatial relation information associating each of one or more transmit beams with one or more of a second set of reference signals and with physical uplink control channel (PUCCH) resources. The method may include, for each of the plurality of TRPs, measuring a pathloss of each common reference signal among the first and second set of reference signals. The method may include selecting a transmit beam and a TRP and sending a transmission to the selected TRP. The transmit beam may be associated with an antenna panel of the WTRU.

摘要： A method for achieving an end-to-end quality of service (QoS) performed by a wireless transmit/receive unit (WTRU) may include receiving a protocol data unit (PDU) and an excess time indication from a source WTRU, and determining an expected latency for a next hop link based on a measure of channel load. It may also include dynamically determining a next hop latency budget based on the received excess time indication and the expected latency and determining resources for transmitting the received PDU based on the determined next hop latency budget. If the resources are available, the received PDU may be transmitted on the next hop using the determined resources.

摘要： Method, apparatus, and systems for determining and transmitting positioning information in a wireless communication network are provided. For example, a method for wireless communications comprises receiving configuration information related to a set of positioning configurations and a small data transmission (SDT), determining, based on the configuration information, that at least one positioning configuration of the set of positioning configurations satisfies a positioning requirement and is associated with a payload size being less than a data volume threshold (DVT) associated with the SDT, selecting, from the at least one positioning configuration, positioning configuration associated with a payload size being closest to the DVT, performing a positioning measurement based on the selected positioning configuration, and sending, using an uplink resource for the SDT, a measurement report based on the selected positioning configuration and the positioning measurement.

摘要： Methods, apparatuses, systems, etc. directed to beam management or, and/or for use in connection with, multiple cells and/or multiple transmission/reception points are provided. Among the methods is a method that may include any of determining first and second reference signals sets (RS sets) associated with first and second sets of beams; receiving information for first and second beam failure recovery (BFR) sets corresponding to the first and second RS sets, wherein the information indicates an RS set associated with candidate beams (CB-RS set) and an uplink resource set for each of the first and second BFR sets; determining beam failures based on the first and second RS sets; selecting the CB-RS set and UL resource set from the first or second BFR set; determining an RS of the selected CB-RS set; and transmitting information indicating the beam failures using uplink resources of the selected uplink resource set.

摘要： Methods, apparatus, and systems are disclosed. In one embodiment, a method of reporting Channel State Information (CSI) by a wireless transmit/receive unit (WTRU) includes receiving configuration information indicating a plurality of CSI reporting configurations and information indicating multiple downlink (DL) semi-persistent scheduling (SPS) resource configurations, wherein each indicated DL SPS resource configuration is associated with a CSI reporting configuration; and receiving an indicator indicating which one or more of the multiple DL SPS resource configurations are active. The method further includes determining one or more measurement time/frequency resources based on a respective CSI reporting configuration or respective CSI reporting configurations associated with the one or more active DL SPS resource configurations; performing one or more measurements on the determined measurement time/frequency resources; and reporting CSI, wherein the CSI is based on the one or more measurements.

摘要： Methods, apparatuses, systems, devices, and computer program products directed to phase-continuous frequency selective precoding are provided. Included among these classes are methods for use in connection with dynamic precoding resource block group (PRG) configuration and with codebook based transmission configuration. A representative of such methods may include any of receiving signaling indicating transmit precoding information; determining a candidate PRG size using any of the transmit precoding information, a rule for determining a PRG size and configured PRG sizes; and configuring or reconfiguring a wireless transmit/receive device in accordance with the candidate PRG size. Another of the representative methods may include reporting a transmission coherence capability of a wireless transmit/receive unit; receiving a codebook subset restriction (CBSR) commensurate with the transmission coherence capability; determining a transmit precoding matrix indices (TPMI) size based on the CBSR; receiving a TPMI; and detecting or decoding the TPMI based on the determined TPMI size.
